FASTENER-SETTING MACHINE.

- Specification of Letters Patent.

Application filed May 22, 1916. Serial No.'99,223.

To all whom it may concern:

Be it known that I, ALBERT E. HUDSON, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain Improvements in Fastener-Setting Machines, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to machinesfor setting eyelets, hooks or similarfastening devices in sheet material. 1

7 An object of'the invention'is to provide a machine of simpleconstruction Which shall be accurate and. reliable in its operation andadapted for a wide range of utility. To this end an important feature ofthe invention resides in operating mechanism of a novel construction,the character of which will be disclosed .in detail hereinafter.

In one of its aspects the invention contemplates improvements in themachine of United States Letters Patent No. 1,244,430, resulting from anapplication of John F. Davey, Serial No. 816,832,.filed Feb. 5,1914. Inthat machine there is employed a power driven setting die. and apunching member arranged to be operated manually preliminarily to thesetting operation. The present invention contemplates, as one feature,power driven mechanism for operating such punching member.

These and other features of the invention will be best understood andappreciated from thefollowing description of a preferred embodimentthereof selected for purposes of illustration and shown in theaccompanying drawings, in which, 7 q

Figure 1 is a view of the machine in side elevation; V

Fig. 2 is a view on an enlarged sca-leof the hopper: and associatedmechanism, shown partly in section;

Fig. 3is a view in elevation .of the side of the machine opposite tothat shown in and I 7 V Fig. 4 153a fragmentary view in frontelevationof portions of. the raceway operating mechanism;

The machine: frame 21s provided with r 5r bearin 's foramain s'haftfi,carrying a driving pu l'ey 4. Glutch'nieclianism, not'shown,

is provided for engaging and disengaging the driving pulley 4 and theshaft 6. The frame is provided with a removable lower aw held in placeby attaching bolts and carrying a stationary upsetting and punchlng tool10. When it is desired to operate upon work of special character, alower jaw of appropriate shape may be substituted for that herein shown.I

The upper portion of the frame 2,is provided with vertical bearings .fora plunger 12' which carries at its lower end the upper or eyeletinserting diel4. Theplunger 1'2 Patented 001;. 21, 191 9.

is connected at itsupper end through a short d link to the forward endof anoperating lever 16. The lever 16 is rigidly secured to a transverseshaft 18 which is journaled in bearings formed in the machine frame,thus k forming the fulcrum of the lever 16. At its rear end the lever 16is connected to the upper link 20 of a pair of toggle links. The

lower link 22 is pivotally mounted upon the stud 52 set, in the machineframe and is oscillated by an eccentric rod 24 which,in

turn, is operated by an eccentric 26 fast on the shaft 6. In thestopped: position of the machine the eccentric 26 occupies its forwardposition so that the toggle links 2022 are held in a broken condition.When the machine is started, the eccentric rod 24' is moved rearwardlyand the toggle links; straightened, occupy ng in this condition aposition substantially parallel to the path of the die 14. 7

Eyelets are suppliedto the. die 14 by a raceway 30 pivotally mountedupon the spin-.

dle 32 which is retained between a pair of ears formed on the frame 2 asshown in Fig. 3.. The raceway normally occupies a position in which theendmost eyelet is maintained in line'with the die 14. 'Whenthe die hasbeen lowered sutliciently to engage the eyelet with its spindle, theraceway is swung outwardly by a trainjof mechanism operated from thelever 16. As herein shown, this mechanism includes a cam bar 36-having abeveled upper end arranged to v be projected betweena roller 34' on therace way SO and a' roller-35 journaled ona part l I of the stationaryframe. The cam'bar36 is connected at its lower end with a lostrnotiolnconnection tothe short 38 fastftoagrock' shaft 40; journaled in -thmaehine]f me. r

The rock shaft 40"PeSses through tlie frame and is provided at itsopposite end with a second arm 42 connected to the lever 16 by means ofa vertically disposed link 44. It will be apparent that when the lever16 is moved to depress the die 14, the cam bar 36 will be elevated bythe mechanism above described and the lower end of the raceway will beswung out of the path of the die 14. The depression of the bar 36,allowing the return of the raceway, will be delayed because of the lostmotion connection between said bar and the arm 38. The omission of suchan arrangement would allow the raceway to strike and frequently to breakthe spindle used for threading the endmost eyelet.

The raceway 80 carries at its upper end a hopper 84 from which theeyelets are supplied to the raceway. WVithin the hopper is disposed anagitator in the form of a brush 82 fast upon the upper end of a shaft 78 which is secured at its lower end to a crank arm 7 It will beunderstood that the agitator is oscillated to cause the eyelets to passoutwardly through the ports of the hopper to the raceway 30. To this endan operating arm 72 is loosely mounted upon the shaft 78 and means areprovided for detachably locking the arm 72 to the crank arm 7 4. Asherein shown, a spring finger piece 76 is arranged in a boss formed onthe outer end of the crank arm 74 and a corresponding socket is providedin-the loose arm 72. The arm 72 is continuously oscillated by the powerof the machine through the bell crank lever 70 pivotally mounted on theframe and connected at its upper end through a pin 71 with a slot in thearm 72. When the arms 72 and 74 are connected by the finger piece 76,the movement of the bell crank lever 70 is transmitted to the agitatorbrush as an intermittent oscillation. In case it should be desired,however, to operate the agitator brush while-the machine remains atrest, as for filling the raceway, the finger piece 76 may be retractedwhereupon the agitator brush is free to be oscillated or rotatedmanually by the crank arm 74. In Fig. 1 the arms 72 and 74 are shown asconnected, as in the usual operation ofthe machine. In Fig. 2 the fingerpiece 76 is shown as retracted and turned so that it is maintained in aninoperative position leaving the agitator brush free to be turned by thecrank arm '7 4.

The punching operation is effected by forcing the workdownwardly uponthe pointed portion of the combined punching and upsetting tool 10. Asherein shown this is effected by a perforated punching member 56 mountedin the forward end of an arm 50, pivotally mounted upon the stud 52before mentioned. The punching member is operated through a pair oftoggle links 58- and 60, the upper of which is rigidly secured to oneend of the journal shaft 18 of the lever 16, and the lower of which isconnected to the arm about mid way between its axis and the tool 10. Inthe stopped position of the machine the toggle links 586O are maintainedin a broken condition with the punching member 56 elevated above thepoint of the punching too]. When the machine is started the lever 16 isrocked, the toggle 58 60 straightened and the punching member 56 forceddownwardly over the point of the punching tool. This operation carriesthe punching member 56 downwardly a sufficient distance to permit theupsetting operation to take place between the body of the tool 10 andthe die 14. If desired the member 56 may be made in separable sectionsas in the machine of the application above mentioned. In order to stripthe eyeleted work from'the tool 10 a spring stripping member 51 issecured to the under side of the arm 50 and this member is elevatedsufficiently before the machine comes to rest substantially to disengage the work from the tool 10.

The machine has been hereinabove described as intended for settingeyelets in sheet material but it will be understood that. with changesin the fastener supplying and setting instrumentalities appropriate forthe accommodation of other fasteners, the machine may be employed forwork of a different character.

The operation of the machine will be apparent from the foregoingdescription but may be briefly outlined as follows:

The work is presented between the strip ping member 51 and the punchingmember 56 with the point at which it is desired to set the eyelet inline with the point of the punching and upsetting tool 10. The machineis then started whereupon the lever v16 is rocked through the togglelinks 2022.

The punching member 56 is immediately depressed forcing the work uponthe pointed end of the tool 10. The inserting die 14 having received aneyelet from the raceway follows downwardly inserting the eyelet in thehole previously formed in the workand in its continued movementclenching the barrel of the eyelet against the upsetting surface of thetool 10. Meanwhile the raceway has been moved to an inoperative positionwhere it is maintained until the conclusion of the setting operation.The lever 16 is then rocked in the opposite direction and the variousparts of the machine returned to their initial positions while; at thesame time, the stripper 51 lifts the eyeleted work from the tool '10.The return of the raceway is, however, delayed until the die 14 and itsspindle are well out of its I claim and desire to secure by LettersPatent of the United States is:
